To me it is not clear what "change the secondary node per another
server" actually means. If you just switch servers, then "drbdadm
disconnect" the resource, put the storage into the new server, adapt the
resource files if necessary (e.g., changed host names) and "drbdadm
adjust" on both ends. This then should result in a partial sync.
Otherwise: What Robert wrote.
